or egg shaped, the object being to provide an applicator head which may be best suited to the particular needs of the operator or the patient.

d and d are plugs and serve as bearings for the shaft 61'' which has an enlargement d to keep it in position.

6- 6 are eccentrically ivoted weights, one threaded to engage similar threads on the l shaft d and the other provided with a To all whom it may concern:

Be it known that 1, WILLIAM F. ACTON, a citizen of "the United States, residing at Norof Fairfield and State of Connecticut, have invented certain new and useful Improvements in Vibrators, of which the following is a specification.

The object of this invention is to provide a portable, mechanical massage vibrator, by means of which one may apply the vibratory treatment to any part of his body conclearance hole 2 venlently; I e are a plurality of circularly arranged de- A further object of this invention is to propressions in the threaded weight a, and e are a plurality of similar circularly arranged elevations on the weight with the clearance hole, and are adapted to engage said circularly vide an instrument of the class described in l which the intensity of vibration may be conveniently adjusted at the will of the operator. V arranged depressions. e is a thumb nut My invention is fully disclosed in the foladapted to engage the shaft 6 and to clamp lowing s ecifications of which the accomthe said weights together. By this means panying rawings form a part in which simithe two weights may be secured to the said shaft in various positions relative to each lar reference characters are used to indicate other and maybe arranged opposite to each similar parts ineach of the views and in which', I other so as to balance, or over each other so Figure 1: is a perspective view of one as to throw their combined weight on one form; Fig.1 2: is a similar view of another side of the shaft 6 form; Fig. 3: is a rear view of the form f is a shaft secured to the gear f, and the shown in Fig. 2 and partly in section. Fig. crank f 3 is a handle for said crank.

41 is a longitudinal section through the form 6 is a shaft to which is secured the bevel shown in Fig. 1; Fig.5: 18 a similar view at right angles thereto, on ,the line 5-5 of Fig. 4', Fig.6 is an enlarged sectional view on the line6- 6 of Fig. 5; and Fig. 7 is a face View of a detail of the device.

In the practice of my invention, I provide a casing'a, comprising two members a and a. forming circular compartments a and a l and necks or elongations a and (t the latter gear f 7 and the pinion f 5 which is engaged by the gear f The bevel gear f engages the bevel pinion f 8 which is secured to one end of the shaft 61 Thus by turning the crank f, the shaft 6 may be caused to rotate rapidly and as the weights on the other end of said shaft are secured thereto eccentrically the desired vibration is produced depending for their rapidity on the speed of rotation of the said crank, and for their intensity on the relative position to each other of the said eccentrically pivoted weights on the shaft (i h shows a special applicator comprising a body member h with outwardly extending l) is a collar which serves to hold the handle fingers h made of rubber or other suitable b in osition. b is a recess in the said 1 material and a metal attachment rod h handle which receives the head of the screw screw threaded at the free end so as to engage b, which is engaged by the threaded neck a. the tube 0 and the plug d. By this means the said handle is securely While I am aware that other mechanical attached to the casing a. vibrators have been made, I believe that the c is a tube attached at one end to the neck shape of the applicator head I herein show a and at the other to the cup shaped head and describe produces anew and useful result externally screw threaded.

A and a are sockets centrally located in a and parts hereinafter dec c is a convex cover for the said cup in that it enables the patient or the operator shaped head and is secured thereto by means to apply the vibratory treatment to different of the bayonet locks c. 0 shows a variation parts of the body with greater ease and eiiiin the shape of the said cup shaped head, ciency thanwas heretofore possible, and while This shape may be I am also aware that in the different forms and is joined at c.

be pear shaped of mechanical massage vibrators, means have spherical as shown or it may simple and eilicient for Lil been in use vibration, the scribe, proves for varying the intensity of device I herein show and dein practice to be the most my purpose.

Having fully described my invention,

What I claim as new and desire to secure by l Letters Patent, is l 1. A mechanical massage vibrator eoml prising a casing, a handle attached thereto,

l l I at one end and a tube at the opposite end, a

shaft rotatably mounted within said tube, a

gear mechanism contained in said casing adapted to rotate said shaft rapidly, a means for actuating said gear mcchanisnn H10 4 weights, each pivoted. at one end on said rotatably mounted shaft, a series of circu l larly arranged depressions in one weight and l a similar series of circularly arranged elevations, on the other Weight, i shaft, adapted to hold said Weights in posi- I tion, and a suitable casing for inclosing said Weights, which said casing is to be used as an I l I a lock nut on said applicator to be applied to the body, sul stantially as shown 2. A mechanical and described.

prising a casing, a handle attached thereto, at one and a tube at the opposite end, a shaft rotatably mounted Within said tube, a gear mechanism, contained in said casing and adapted to rotate said shaft rapidly, a means for actuating said gear mechanism, a Wedge shaped weight, screw threaded at its extreme end on said rotatably mounted shaft, a similar Weight pivoted at its extreme end on said rotatably mounted shaft, but ada ted to turn freely thereon, a means for lociring said freely moving Weight in any desired position with reference to the other Weight, and a suitable casing for inclosing said Weights, which said casing is to be used as an applicator to be applied to the body, sub stantially as shown and described.

in testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this 13th day of TM. F. ACT ON April, 1908.
